XMAP has a wide variety of maps available for use. Due to this, it can be very time-consuming to try and find a particular layer by scrolling down the layers list.
Using the Layer Search tool
To search for a particular layer by name, click the magnifying glass symbol. This is located above the map window in the left toolbar.
This will give you a search box that you can click and type in your chosen layer's name. Any map that has corresponding letters to your search term will appear in the map window.
To choose one of your map search results, left-click on the given layer. This will apply it to your map.
